Grundfos SB 3-45AW Submersible Pressure Pump

The Grundfos SB is a submersible pump for the pumping of clean water. It is designed for use in domestic applications. The pump itself is very silent, and when installed underground in a rainwater collecting tank or well, noise will never become an issue. The SB pump requires an external controller, like Pressure Manager, for automatic operation.

The floating suction strainer draws the water from just below the water surface where the water is clean and free from solid particles.

Grundfos SB Pump Features

Noiseless operation The SB pump emits no noise when submerged and is therefore a noiseless alternative to non-submersible pumps.

Robust design The SB pump is built of composite and stainless steel materials which are resistant to corrosion.

Thermal overload protection The single-phase model is effectively protected against any accidental overload, by built in thermal protection.

Dry running protection The SB pump is protected from dry running, by means of the function of the flow switch.

Automatic operation The flow switch for the SB pump ensures automatic operation by means of the water level in tank.
